When the anti-sliding support frame 340 and the cambered surface support frame 350 absorb deformation in place, the anti-sliding support frame 320 absorbs thrust of multiple layers of sliding strip accumulation layers to generate warping, so that the sliding of the whole anti-sliding support frame 320 is shortened, after a preset period of time, an anti-sliding outer contour support in the deformation direction is excavated and hung, the height of a sliding slope deformation layer and the thrust of the sliding slope deformation layer are analyzed and judged through the deformation of the anti-sliding support frame 340 and the cambered surface support frame 350, the height of the sliding slope deformation layer and the thrust of the sliding slope deformation layer are further analyzed and judged through the warping of the anti-sliding support frame 320, the change of the thrust of the sliding slope of the multiple layers of sliding strip accumulation layers is pre-aimed at the change of the thrust of the sliding slope of the multiple layers of sliding strip accumulation layers, the local stress reinforcement and adjustment of the anti-sliding support are carried out, and the stability of the sliding strip accumulation layers of the multiple layers of the sliding strips is improved.

When the thrust and the direction of the multilayer slide belt stacking layer change, the jacking block 520 resets and extrudes the slide insert support frame 320 under the action of the energy-absorbing spring 550, so that the slide insert support frame deforms and resets. After a period of time is preset, the engineering personnel analyze and calculate the integral thrust of the multilayer slide belt accumulation layer through the integral change of the energy absorption pipe 540, and stress reinforcement and adjustment are performed on the anti-skidding support center aiming at the change of the landslide thrust of the multilayer slide belt accumulation layer in advance, so that the anti-skidding stability of the landslide of the multilayer slide belt accumulation layer is improved.
In addition, when the anti-skid strut 340 and the arc-shaped strut 350 are extruded by the multilayer slide belt stack layer, the arc-shaped strut 350 in the stress direction is stressed and then bent to cause the overall shortening, and outside personnel judge the general direction of the landslide by the shortening degree of the arc-shaped strut 350 exposed out of the ground, namely the shortest arc-shaped strut 350 is the main direction of the landslide. After the cambered surface strut 350 is stressed and bent, the corresponding jacking block 520 is extruded, the pressure head 533 at one end of the energy absorption seat 530 is driven to extrude the expansion joint 541, the expansion joint 541 is extruded and stressed to drive the energy absorption pipe 540 to extend integrally, the warning mark is arranged at the upper end of the energy absorption pipe 540, and outside personnel can judge the failure condition of the anti-slide pile through the identification of the energy absorption pipe 540 exposed out of the ground. When the anti-skidding support is not influenced, external personnel are prompted to avoid landslide geological disasters through landslide direction early warning and anti-skidding pile failure early warning, and landslide accidents are reduced.
The above embodiments are merely examples of the present application and are not intended to limit the scope of the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that like reference numerals and letters refer to like items in the following figures, and thus once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
